GE MDS SECURITY SUITE

Today, the operation and management of an enterprise is becoming 
increasingly dependent on electronic information flow. An 
accompanying concern becomes the security of the communication 
infrastructure and the security of the data itself.

The MDS entraNET is capable of dealing with many common security 
issues. 

Table 1-2

 profiles security risks and how the MDS entraNET 

provides a solution for minimizing vulnerability.

Table 1-2. Security Risk Management

Security Risk

The

 

MDS entraNET Solution

Unauthorized access to the backbone 
network through a foreign remote radio

Approved Remotes List

Only radios on the Approved 
Remotes list connect

“Rogue” AP, where a foreign AP takes 
control of some or all Remote radios and 
thus remote devices

Approved AP List 

A Remote connects only to APs on 
its Approved AP List

“Dictionary attacks”, where an intruder 
runs a program that sequentially tries to 
break a password

 Failed log-in lockdown 

After three tries, a transceiver 
ignores log-in requests for 5 min. 
Critical event reports (traps) are 
generated as well.
